Application filed October 27, 1917. Serial No. 198,787.

To all whom t may concern:

Be it known that I, JOHN M. RICHARDSON, a citizen of the United States, and resident of Milwaukee, inthe county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Cushion-Seats; and I do hereby declare that the following is a full, clear, and eXact description thereof.

My invention relates to certain new and useful improvements in cushion seats and refers more particularly to the method of cushioning and coveringthe seats.

One object of the present invention is to provide a method of constructing cushion seats, such as davenports and the like which will dispense with the usual spiral springs utilized to provide the cushion eect.

Another object of my invention is to provide means for temporarily sagging the i mesh spring while the liller and covering is being secured thereto.

A further object of my method of con-- structing cushion seats is to so construct the same as to have the supporting or sustaining spring always under tension, even after the filler material has become packed..

A still further object of my invention is to provide means whereby the distorting of the edge of the seat is prevented and the edge of the seat is held in normal position.

With the above and other `objects; in view which will appear as the description proceeds, my invention resides in the novel construction, combination and arrangement of parts substantially 4as hereinafter described and more particularly deifined by the appended claims, it being understood that changes in the precise embodiment of the herein disclosed invention may be made without departing from the spirit of the invention.

In the accompanying drawings, I have illustrated one complete example of the physical embodiment of my invention constructed according to the best mode I have so far devised for the practical application of the principles thereof, and in which:

Figure 1 is a t'op plan view of a davenport, or the like, the spring being retained in sagged position preparatory to forming the cushion seat thereon.

Fig. 2 is a perspective view of a transverse bar utilized for detachably retaining the spring in sagged position.

Fig. 3 is a longitudinal sectional view through a davenport, or the like, seat with the cushion seat there applied and the spring held in sagged position, and

Fig. 4 is a view similar to Fig. B with the transverse bar removed and the spring allowed to assume its normal position.

Referring now more particularly to the accompanying drawings, l and 2 represent the side and end sills of a rectangular frame of a davenport or any other suitable cushion seat and secured to each end sill 2 is an angle-iron 3 having suitable perforations therein for receiving the outer ends of suitable contractile spiral springs t having their inner ends secured to the outermost portions of a linked mesh sustaining spring'. As will be readily apparent, the sustaining spring 5 is held in taut position by means of the contractile springs 4.

In contradistinction to the former method of utilizing the spiral expansile springs for the cushion of seats of this character, a suitable fller 6 of hair, feathers, cotton, or the like, is confined between spring 5 and the cover 7 having its edges secured to the sills of the frame. Before placing liller 6 or cover 7 over spring 5, the spring is sagged and held in that position by means of-a transverse bar 8 having its ends abutting the under side of side sills l and carrying suitable hooks or keepers 9 which engage certain of the links of the sustaining spring and thus detachably retains the same in the position depicted in Fig. 3.

After the spring has been secured in sagged position by means of bar 8 and its keepers, the filler 6 is placed thereon and then cover 7 secured in place, when keepers 9 are detached from the spring and bar 8 removed. The sustaining spring 5 will then return to the position depicted in Fig. 4, the same being slightly sagged in the center and consequently held under stress to compensate for any packing of liller 6, as will be obvious.

Referring now more particularly to Fig. 1, disposed adjacent each peripheral edge of sustaining spring 5 is a suitable flat strip 10 which has its ends connected with angleiron 3 by means of springs 11 similar to spring 4, and to prevent lateral sagging or movement of strips 10, suitable diagonal braces 12 are employed. Braces 12 have their inner ends pivotally secured to either end sill 2 or angle-iron 3 and their outer ends secured to the strip 10 adjacent their outer ends as at l13, Whereby vertical movement thereof is permitted and lateral movement prevented.

As vvill be readily understood, strips 10 serve to prevent the finished seat from getting out of shape in that the springs 11 Will serveV to return lstrip 10 to normal position and braces 12 While permitting vertical movement Will prevent lateral movement, and thus lessen the stress upon the edges of sustaining spring 5.

I claim l. rlhe herein described method of constructing cushion seats which consists in first laying a sustaining spring, in holding the spring in sagged position, in placing a suitl able iiller thereon, in covering the iller, and

inally in releasing the spring.

2. A device of the class described comprising a frame, a sustaining spring carried thereby, means for sagging the spring to assist in securinga cushion seat thereon, and means forfpreventing the edges of the spring from sagging, substantially as described.

3. A. device of the class described comprising a frame, a sustaining spring carried thereby, means for temporarily sagging the spring to assist in securing a cushion seat thereon, and means for preventing the edges of the spring from sagging, substantially as described.

4. A device of the class described comprising a Jframe, a sustaining spring carried thereby, a cushion seat carried by said spring, and means for retaining the spring in sagged position While the cushion seat is being formed, substantially as described.

5. A device of the class described comprising a frame, a sustaining spring carried thereby, a cushion seat carried by said spring, and detachable means for retaining the spring in sagged position while the cushion seat is being formed, substantially as described.

6. A device of the class described comprising a frame, a sustaining spring carried thereby, a cushion seat formed thereon, and means for releasably retaining the spring in sagged position While said cushion seat is being formed, said means comprising atransverse bar engageable with the sides of the "frame, and means carried thereby for engaging said spring substantially as described.

7. A device of the character described comprising a frame, a sustaining spring carried thereby, a strip disposed at the side of said spring, resilient means engaging the frame and the ends of said strip to retain the same in position, and a brace for said strip.

8. A device of the character described comprising a frame, a sustaining spring carried thereby, a iiexible flat strip disposed at the side of said spring, means resiliently securing the ends of said strip to the frame, and means for preventing the flexing of said strip in more than one plane.

In testimony that I claim the foregoing I have hereunto set my hand at Milwaukee, in the county of Milwaukee, and State of Wisconsin.
